Abstract
- Apara-nitrophenol sensor based on a 5-sulfosalicylic acid doped polyaniline nanorods modified glassy carbon electrode is reported. The formation of 5-sulfosalicylic acid doped polyaniline was characterized by Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The electroactivity of the 5-sulfosalicylic acid doped polyaniline nanorods was studied by cyclic voltammetry and differential pulse voltammetry and high response was observed for the reduction ofpara-nitrophenol. The calibration curve forpara-nitrophenol was linear from 6.7 × 10−6 M to 112.1 × 10−6 M. The sensitivity and limit of detection were 24 nA µM−1and 3.2 × 10−6 M, respectively. The sensor was simple, inexpensive, and employed for the determination ofpara-nitrophenol in tap water with recoveries from 97.6 to 101.0%. [ABSTRACT FROM PUBLISHER]
